### Added

- Implement the `hidden` escape sequence (`echo -e "\e[8mTEST"`)
- Add support for macOS systemwide dark mode
- Set the environment variable `COLORTERM="truecolor"` to advertise 24-bit color support
- On macOS, there are two new values for the config option `window.decorations`:

        viewport to extend to the top of the window.
    - `buttonless` - Similar to transparent but also removed the buttons.

  available, otherwise the `xterm-256color` entry is used instead

  entry (which also advertises 256 colors)

### Deprecated

  of `true` or `false`, respectively.
